Abstract: Biodiesel with fuel additives has been gaining increased attention from engine researchers in view of the energy crisis and increasing environmental problems. The present work is aimed at experimental investigation of Isobutanol as an additive to the diesel- biodiesel blends. Experiments were done on a 4-Stroke single cylinder diesel engine by varying percentage by volume of Isobutanol in dieselbiodiesel blends. The effect of Isobutanol on brake thermal efficiency, brake specific fuel consumption, cylinder pressure, heat release and exhaust emissions were studied. It was Ghose M K found that brake thermal efficiency is increased with increase in blend percentage both with 5% and 10% Isobutanol. Addition of Isobutanol shows negative impact on Brake specific fuel consumption (BSFC) which decreased with blend percentage while it increases with Isobutanol percentage. CO emissions and smoke capacity decreased significantly while NOx emissions decreased marginally with the increase in Isobutanol percentage
